The `daylight saving` purpose is intriguing. I'm very curious why people long time ago, decided to change clocks, instead of work/school start and finish times. Like we start in April at 8:00 am, and in November, at 9:00.

I believe the reason is that it costs less to move the hands of a clock than to print and distribute new timetables for trains, buses, etc. That could cost less today because we use much less paper, but updating web sites and databases is still a large amount of work. It's far easier to communicate to all the country when to move the clock and keep everything else the same.

  It actually costs in an entirely different way, when you screw with everybody's sleeping schedules, cause accidents with wildlife getting surprised by brisk changes in traffic peaks. Personally, I never dealt well with the change, either, so this means I have one less thing to worry about in pollinosis season. Good riddance.

    Do you have any credible sources that say wildlife is affected in any way by daylight savings?

      I don't have a source, but my understanding was that deer tend to learn when it's safe to cross the road. When all of a sudden people change their driving habits by an hour, deer start to get hit by cars that they didn't expect to be there.

  Where I live, we get both. They change both the time and the bus schedules in accordance with the seasons.

Because, even to take the simplest case of just considering workplaces and schools, unless all workplaces and all schools shift their hours by the same amount on the same day--along with all the transportation systems associated with them--they'll be out of sync when some change and some don't. And, even if you assume that such perfect synchronization is possible and perfectly communicated (by everyone having different summer and non-summer hours), why not just make the change centrally instead?

Growing up in India (which has no DST), that's how it worked. School would start later during the winter months.

  Bravo India! You 1. Don’t have this stupid time shift. 2. You don’t patronize your citizens’ ability
